skip_phase_fitting(label, phase)

aips_like_phase_fitting(amplitude, phase, pol_axis, freq_axis, telescope, u_axis, v_axis, user_phase_fit_control, label)

create_phase_model(parameters, wavelength, telescope, u_axis, v_axis)

Create a phase model with npix by npix size according to the given parameters :param parameters: Parameters for the phase model in the units described in _phase_fitting :param wavelength: Observing wavelength, in meters :param telescope: Telescope object containing the optics parameters :param u_axis: Aperture’s U axis :param v_axis: Aperture’s V axis

Returns:

clic_like_phase_fitting(phase, freq_axis, telescope, focus_offset, uaxis, vaxis, label)

phase_wrapping_jit(phase)

Wraps phase to the -pi to pi interval :param phase: phase to be wrapped

Returns: Phase wrapped to the -pi to pi interval
